EMERGENCY SUPPLY FOR FUEL-COMBlISTION ENGINES.

Application filed May 29, 1923. Serial No. 642,200.

T 0 aZZ whom it may concern:

Be it known that 1, CHARLES M. Donovan, a citizen of the United States, residing at Wichita, county of Sedgwick, and State of Kansas, have invented certain new and useful ImprEements in Emergency Supplies for Fuel-Combustion Engines, reference being had to the accompanying drawings, which form a part of this application.

My invention relates to emergency'supply for internal combustion engines.

The objects of my invention are as follows:

First, to provide means as warning for the exhaust of the gasoline in the fuel tank.

Second, toprovide means for consuming the remainder of gasoline in said tank.

Third, to provide an emergency supply for the carburetor when the vacuum tank contents has been exhausted.

Fourth, to operate the said means from the dash of the car.

Referring to the drawings, Fig. 1 isan elevation of the system assembled.

Fig. 2 is a fragment of the frame cowl and dash showing the position of the vacuum and emergency tank as placed.

Fig. 3 is a front view of the tanks as positioned on the cowl.

Fig. 4 is a sectional view through the by-pass valve.

Fig. 5 is a transverse section of the valve.

'Fig. 6 is a front view of the dial of tank, connecting same with the base of indicating valve.

' Fig. '7 is a side view of the dial.

In Fig. 1, 2 is the fuel tank, 3 is the supply pipe. 4 is' the emergency pipe, said pipes being connected with a valve 5. 6 is a pipe connecting said-valve to vacuum tank 7. 8'is an emergency tank, said tank being interposed between the vacuum tank 7 and the carburetorv 13, the said tank 8 is connected to the base of the vacuum tank 7 by a pipe. 9 and on the opposite end of said bank is a pipe 11 connecting with pipe 12 which isthe direct supply from the vacuum tank 7 to the carburetor 13, and interposed in pipe 11' is a valve 10 operated by'a lever 14, said lever connected to the valve '0 linder as means for rotating said valve fin dispensing the gasoline of the emergency tank 8 to the carburetor and said lever having a spring 15 as 16 is a cord functioning as means for opening said valve.

Referring to the valve,Figs. 4 and 5,

24 is the body of the device, having an outlet 25 and two inlets 26 and 26'. 27 is a frusto conical valve member closely fitting in a bore 28, of same taper. 29 is a disc having its bearing on the body of the valve, through which passes a rod 30, having a nut 31 as means for tensioning said cylinder to a liquid tight position in said bore. Said cylinder having an opening 32, adapted to register with openings 26 and 26. The opening or aperture passing. through said cylinder 27, is-flared from the center outward as shown at 33, the object of which is to provide free flow of'the fuel from either pipe 3 or 4 through the pipe (3, which is connected to the opening 25. The valve 27 is rotated by means of a rod 30, said rod passing through a dial 31 and on the end of said rod is placed a finger 32, said finger engaging with stop blocks 33 and 33'," and on the rim of said dial are the words supply, and reserve, the object of which will be more fully explained hereinafter. 16 is a cord as heretofore described, connecting with the emergency tank valve lever 14, extending upward and through the dash board and on the end of said cord is a knob 34 functioning as means to 0 on said valve as heretofore described.

y emergency device may be applied to any make of automobile, tractor or other vehicle, by supplying the valve and parallel pipes, 3 and 4 and placing the emergency the vacuum tank, and connecting it with the pipe extending from the tank to the carburetor.

The principle of my device is that a liberal amount of gasoline may be left in the. tank as a warning that the supply is 'low and as at this instant the vacuum tank .emergency portion of the oil left in the tank, and at this instant the valve is turned to the emer ency mark on the dial which allows the alance of the oil to be consumed, making it possible for the operator to reach a filling station.

Such modifications may be employed as fall within the scope of the appended claim and having thus described my invention,

what I claim as new, and desire to secure by Letters Patent is:

In an emergency supply for fuel combustion engines. a fuel tank, an internal combustion engine having a carburetor thereon, a vacuum tank, a pipe line con necting said vacuum tank with said engine, an emergency supply tank positioned between the base of said vacuum tank and said engine carburetor, a pipe line connecting said emergency tank with the base of the vacuumtank and the pipe line between k said vacuum tank and the carburetor, a valve positioned in the pipe line between said emergency tank and the pipeline leading from the vacuum tank to "the carburetor, means for rotatingsaid valve, two pipes extending into the fuel tank, one terminating in proximity to the bottom thereof, and the other at a substantial distance.

above the bottom, a valve for selectively placing either of said pipes in communication with the vacuum tank, a rod to operate the valve and a dial finger on the rod adapted toindicate the position of the valve;

CHARLES M. DONOVAN.
